CNMQ160812T-A27T WKP35S milling indexable insert by Walter Tools — Rhombic 80°, Tiger·tec Silver coating

CNMQ160812T-A27T WKP35S is a high-performance milling insert designed for versatile metalcutting tasks in steel and cast iron, combining a negative rake face and dedicated chip control for stable, productive machining

• Tiger·tec Silver coating for long tool life
• Suitable for steel (P) and cast iron (K)
• Rhombic 80° geometry for flexibility
• A27T chipbreaker for reliable chip control

Longer tool life through advanced coating technology

The Tiger·tec Silver coating and the WKP35S grade deliver a balanced performance between wear resistance and toughness. This coating technology reduces abrasive and thermal wear, which translates into longer tool life and fewer changeovers on the shop floor. For operations where consistency counts, the coated carbide composition ensures reproducible results under varying cutting conditions, supporting sustained productivity and lower tool costs per component.

Robust geometry and negative rake for heavy-duty cuts

The Rhombic 80° shape with a 0° negative rake offers a stable cutting edge that resists deformation during heavy cuts and interrupted machining. The geometry provides good support for the cutting edge, enabling higher radial engagement when required. The combination of the insert form and its corner radius 1.2 mm helps to maintain surface integrity while reducing the risk of chipping, making it suitable for both roughing and medium finishing operations.

Controlled chip formation and material suitability

Equipped with the A27T chipbreaker, this insert produces predictable chip shapes across a range of feeds and depths, improving evacuation and reducing recutting. The specification P / K indicates that the grade is optimised for both steel (P) and cast iron (K) according to ISO material groups, so users can rely on the insert for shop-floor versatility. The coated carbide substrate of the WKP35S grade balances wear resistance and edge stability for these material families.

Practical guidance for effective application

The insert’s designation and form factor allow straightforward integration into common milling tool holders configured for 16 mm inscribed circle dimensions and an 08 thickness profile. When paired with appropriate cutting data and clamping rigidity, the insert yields consistent surface finish and predictable tool life. For parameter selection, start with manufacturer-recommended speeds for the workpiece class and tune feeds to achieve the intended chip thickness while monitoring temperature and wear patterns.
